Spreading the load on your shoulders
A well-adjusted harness and machine makes work much
easier. Adjust the harness for the best working position.
Tension the side straps so that the weight is evenly
distributed across both shoulders.
Correct height
1 Forestry clearing
The machine should be supported in a harness when
forestry clearing so that the cutting equipment is angled
slightly forwards in relation to the ground. Adjust the
height using the strap on the harness for the support
hook.
2 Grass clearing
The machine should be supported in a harness when
grass clearing so that the cutting equipment is parallel to
the ground.

ASSEMBLY
Correct balance
1 Forestry clearing
The machine is balanced by moving the suspension ring
on the machine forwards or backwards. On some models
the suspension ring is fixed, however, this will then have a
number of holes for the support hook. The machine is
correctly balanced when it freely hangs horizontally from
the support hook. In this way the risk of hitting stones is
reduced if you need to release the handlebar.
2 Grass clearing
Let the blade balance at a comfortable cutting height, i.e.
close to the ground.
